consists the iiovel life'atures of 'co'nstructlon more fully'iset forthin are spec-1- where it may b'esecurely held in'e'i lymo-v ing arotatable cam a slight degree forclainping theextensible rod inposition. Afurt-her'o'bjec't is to provide adjustment for the clampingmechanism of the brace rods so as to take up play that results fromwear. Furthe r objects are to provide a brace rod that is positive inits action, one that is durable and one that may be manufactured atcomparatively small cost. Further and other objects willbe betterapparent from a detailed description of the invention in connection withthe accompanying drawings, in which Figure 1 is a perspective view of acasement window showing my improved brace rod applied thereto; Fig. 2 isa middle longitudinal section taken through the assembled brace rod;Fig. 3 is an elevational view of the tube and clamping mechanismsurrounding the rod or core of the device; and Fig. 4 is across-sectional detail taken on the line 4- 3 of Fig. 2.

Referring to the drawings, it will be observed that my improved bracerod is formed of two members, a non-sliding casing A and a sliding rodB, one end of which is supported in said casing. The casing A has aswivel connectionl with a bracket 2 that is adapted to be fixed on thesill S of window frameF; The outer end of rod B is pivotally connectedto a bracket 3 which is securely fixed to a casement window W hinged inthe frame F.

The outer end of easing A is provided with an annular shoulder at andthe inner end is screw-threaded to receive a plug 5 having a head 6.Positioned within the casin A and in contactin relation with lug 5 1s aring cam 7 having its inner e ge 8 camshaped to cooperate with the camformation 9 formed on the adjacent edge of a sleeve 10 within casing Aand extending through a considerable portion thereof. Between the outeredge 11 of sleeve 10 and shoulder 4 of casing A is arranged a series ofclamping members comprising in the order named a ing into slot in,sleeve 10, said slot permit ting reciprocation of isjald'sl'eevebutno'ro wedge ring 12, a fibre contracting i'ing'13; a

wedge ring '14, litre contracting rin 15,

rings ali1dQ15' are split re pectively as designated at 17 andlS andtheir edgesia;

19 jarid 20*, 20fiespecti velyhre beyelled to scope-ate with s oping orincurred edges 21 or i'ing12, a2, 22 err-m 14, are 23' of an gie.

The sleeveio is held against reas n y a l i i setscrew 24 traversingcasing A and enter- 'taeen thereof. a na- 26 isprwiaea is seein A, and athumb screw 27 traverses said slot and is screwed into the ring cam 7,said slot 26 being of suificient length to allow the thumb screw 27 tobe oscillated back and forth and being somewhat wider than the shank ofthe thumb screw for a purpose hereinafter to become apparent.

hen it is desired to open the window W, the cam 7 is rotated by means ofthumb screw 27 in the direction of the arrow (Fig. 4) which releases anytension on the sleeve 10 and, of course, allows the fibre rings 13 and15 to expand to their normal diameter, thus unclutchingthe rod B andallowing it to slide freely in the casing A. Having adjusted the windowto the proper position, the cam 7 is rotated in the direction oppositeto that indicated by the arrow (Fig. 4) whereby the cam-shaped edge 8will force the sleeve 10 outwardly because of the co-action of the edge8 and edge 9 of said sleeve and the inability of the sleeve 10 torotate. The outward movement of sleeve 10 causes rings 13 and 15 to besqueezed together by the action of wedge rings 12, 14 and 16, saidcontraction of rings 13 To permit the ring cam 7 to move further intothe casing when the plug 5 is adjusted for wear, there is clearanceprovided between the sides of slot 26 and thumb screw 27.

From the foregoing it will be seen that I have provided a brace rod thatmay be released or locked with but a very slight movement of theactuating cam, and one wherein there'issultable provislon made forovercoming play or lost motion due to Wear.

1. A brace rod for casement windows, or the like, comprising atubularcasing, aplu rality of clutch members within said casing, a rod adaptedfor sliding movement within said casing, means for actuating the clutchmembers to grip and release said rod, and

means for effecting adjustment for compensating against play due towear.

2. A brace rodfor casement windows, or the like, comprising a tubularcasing, a plu rality of ring clutch members within said casing, a rodtraversing the clutch members and adapted for sliding movement withinsaid casing, and meansfor actuating the clutch members to gripandrelease said rod.

3. Abrace rod for casement windows, orv

the like, comprising a tubular casing, a sleeve adapted for longitudinalmovement Within said casing, a plurality of ring clutch mem- Havingdescribed my invention, I claim: f

bers confined between said sleeve and abutment at one end of the casing,a rod adapted for movement through the clutch members,

and means for imparting longitudinal move ment to the aforesaid sleevefor effecting a contraction of the clutch members to grip said rod.
